Identity & game plan
- Win condition: Synchro Summon Stardust Dragon, Shooting Majestic Star Dragon or Adamancipator Risen - Tiamite off Synchron/Stardust/Junk tuners, then protect the board with negates and Dark Hole/Raigeki-style sweepers; Assault Mode Activate / Assault Synchron chains into /Assault Mode Synchro bodies (Stardust Dragon/Assault Mode)
- Turn 1 (going first): Normal Summon a Tuner (Junk Synchron, Stardust Synchron, Full-Speed Warrior or Assault Sonic Warrior) to search, then Synchro into a Level 8+ boss with the remaining monster; hold Ash Blossom or Infinite Impermanence for the opponent's turn
- Turn 2 (going second): Hand-trap the opponent's starter with Ash Blossom, Ghost Belle or Infinite Impermanence, then Synchro through the gap; sweepers (Dark Hole, Raigeki, Lightning Storm) reset an established board
- Recovery: Stardust Synchron and Stardust Trail can be Special Summoned from hand or GY and Junk Meister or Full-Speed Warrior search, so the engine partially rebuilds from GY
- After siding: No Side Deck is registered (side_count 0), so there is no post-side plan; the deck cannot adapt between games
Why it scores here
The deck has a real Synchro engine: several Tuners (Stardust Synchron, Junk Synchron, Assault Synchron, Ghost Belle) reach Level 8+ bosses such as Stardust Dragon and Shooting Majestic Star Dragon, and the Extra Deck has 15 Synchro monsters for flexibility. Interaction is broad and layered, with about 20 negation-text cards and 29 removal-text cards, including two Ash Blossom copies and Ghost Belle as hand traps. The score is held down by the foundation: 70 of 72 copies are off the exact Synchron name, the deck has no combo evidence, and the 57-card Main Deck carries many one-copy tech cards and spells that compete for slots, which raises brick risk. Popularity and archetype share were not credited, and card scores were not averaged. The score is capped at 30 because the deck is Illegal: Naturia Beast is Forbidden in OCG and cannot be run at all.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 52 | Searcher-text group P(>=1 in opening 5) ~0.74 and 2-card Tuner bootstrap plausible, but no starter list or core-card stat is available (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | 21 spells and 7 traps in a 57-card Main Deck with 20 one-copy cards suggests frequent dead or redundant hands; guide snippet cites brick and instability (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Ceiling reaches Level 8+ Stardust and Majestic bosses from a few Tuners, but no recorded combo boards exist to verify it (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No combo boards supplied; median output cannot be measured and the guide's brick comment points to a low median (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple negates (Ash Blossom, Ghost Belle, Infinite Impermanence, Stardust Dragon) and GY recursion (Stardust Trail) give some route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Recursion from GY via Stardust Synchron and Stardust Trail, with search-heavy Tuners, offsets spend; no resource signature exists (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | Layered negation and removal: 20 negation-text and 29 removal-text cards, with Stardust Dragon and Adamancipator Resonance on the board (Observed from card text, Inferred in use) |
| D8 | Going-Second & Board-Breaking Power | 55 | Sweepers (Dark Hole, Raigeki, Lightning Storm, Harpie's Feather Duster) and Majestic Star Dragon give going-second board-breaking; no going-second split is recorded (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | High-ATK bosses (Majestic Star Dragon 4000, Psychic End Punisher 3500, Tiamite 3300, Stardust Dragon 2500) convert advantage (Verified stat, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 45 | Mixed-archetype Main Deck with 36 distinct cards, many singletons and the 57-card count, lowers compactness (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 65 | Extra Deck is 15 Synchro monsters with a useful spread of Levels and effects; no Extra Deck mandatory-slot data (Verified composition, Inferred use) |
| D12 | Side Deck Adaptability | 10 | No Side Deck is registered (side_count 0), so there is no adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No dated meta or tournament link; only archetype context exists, so this is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Synchro lines and many interaction windows with one-copy tech cards are demanding to pilot (Inferred) |
How the score was computed
Strategy profile: Midrange primary; Toolbox secondary noted but not blended numerically. Structural ≈ 50, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-6); no side deck (-3). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(35) + modifiers(-9) = 38 uncapped; Illegal deck capped to 30 per rubric Step 2
Probability & combo summary
- Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Layered negation and removal (20 negation-text, 29 removal-text cards)
- Strong Synchro finishers with a 15-card Extra Deck
- Multiple Tuner routes and GY recursion
Weaknesses
- Illegal: Naturia Beast is Forbidden
- Low archetype purity (2.8% exact name) and many one-copy tech slots
- No Side Deck
- No combo or win-rate evidence
Critical choke points
- A Tuner in hand is required for almost every Synchro line
- Naturia Beast cannot be legally run, so the list has no valid version as built
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Naturia Beast | A legal Synchro with the same Level-and-Tuner role, e.g. a second Junk Speeder (Level 5, 1 copy in deck; limit 3) | Forbidden cards make the list illegal; fixing this is required before any normal score can apply |
| 2 | One or two one-copy tech cards (e.g. Harpie's Feather Duster or Crossout Designator) | A third Tuner or a second copy of an engine card already in the list | Reduces brick risk and increases Tuner access for the core Synchro engine |
| 3 | None | A Side Deck of 5-10 cards aimed at the most common format threats | Side Deck is empty, so adaptability is zero for best-of-3 |
Evidence & confidence
- Verified: Naturia Beast is Forbidden and over the copy limit (legality); Main 57 and Extra 15 are within OCG size rules; Side count is 0; Card texts and stats match the evidence file
- Observed: No combo boards exist (combos_evidence total 0)
- Inferred: Searcher-text probability 0.74 and hand-trap 0.56 estimates; Consistency, brick, and interaction reads from card text and composition; Going-first and going-second estimates
- Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry for going-first, going-second, matchup, or brick rate Meta Power is Provisional without a dated metagame sample Usage core cards (Mulcharmy Fuwalos, Droll & Lock Bird) are not in this deck, so it deviates from the archetype-standard core
